I decided to make a replurkable list of answered questions from Game FAQs as well as some other articles I've found re: unlocking items and what certain things do.

Stamp book list from a Japanese site. I ran it through Google Translate but if that doesn't work properly this is the direct link

Obv not 100% accurate in the translation department but it should help in regards to stamp collecting.

a question about allowance and the alarm. Having tested it myself, no, the alarm does not work in sleep mode. Your 3DS has to be open.

However if you do put a 'loid to sleep and leave it open certain events will happen, like getting the "Nightmare" card. Also they dance in their sleep.

what the mic button does in the room and in the song list

Apparently it's Voice Recognition on both!

this and this article here has to do with the "befriending" portion of the game.

The article specifically detailing how you use that to unlock the PJ costumes, which takes about two weeks.

Basically pamper them. A lot. XD

Further information about the rooms and items with some notes about what a few of the items do

(They ride around on the Roomba! Imma do that )

"Role Model" mode and other notes about listening to music as opposed to just playing

Song list with some clearing information

The song list from the wiki with basic clearing information as well as difficulty

Costume list from the wiki with unlock information sans PJ mods with a note that random costumes will go half price in the market on Wednesdays.

Puyo Puyo rules and a note about strategy not very detailed tho

Mikuversei rules

How to open up multiple voice tracks for songs that have them

how to use the dance studio

and how the data sharing works if you didn't already know

And that's all I've found for now, but if I stumble across anything else, I'll add it! feel free to add your own info that you've discovered along the way, and happy Miku-ing! [happydance]

about the Tsukimi set given out this month!
